INDEX DEVICE John W. Robertson, Lakewood, N. Y., assignor to Art MetalConstruction Company, Jamestown, N. Y.

Application March 11, 1958, Serial No. 720,646 '4 Claims. (Cl. 40-23)This invention relates to label or index strip holders, such as are usedon visible filing equipment and the like. More particularly, examples ofsuch applications include label holding tabs as used on index cards andguides, separating cards, and reference files, and all such devices asrequire identifying index or indicia bearing labels.

One object of the present invention is to provide an improved indexstrip holder for the purposes aforesaid which is of such form as torender the mounted label more readily visible and legible.

Another object is to provide a holder as aforesaid which is of suchconstruction as to facilitate insertion and holding of the label inimproved manner.

Another object is to provide an improved label holder as aforesaid whichis adapted to contain the mounted label in improved manner againstaccidental displacemerits.

Another object is to provide a holder as aforesaid which is relativelyinexpensive to manufacture, yet rugged and invulnerable to servicehazards.

Other objects and advantages of the invention will appear from thespecification hereinafter.

In the drawings:

Fig. 1 is a front elevational view of a holder of the invention;

Fig. 2 is a sectional view taken along line 11-11 of Fig. 1; and

Fig. 3 is a fragmentary perspective view of an index book cover,mounting thereon a holder of the invention and illustrating the mode ofinsertion of a label or index strip therein.

As shown in the drawing, the holder of the invention, designatedgenerally at 10, is preferably formed of an extruded stock of a suitabletransparent synthetic plastic material, such as for example the materialcommercially known as Tenite. The stock piece is formed sectionally asshown in Fig. 2 to include a bottom skirt portion 11 which is adapted tobe mounted by any suitable means such as riveting, or otherwise fixed asby slip-fitted insertion between panel portions 12-14 of the devicewhich the holder is to identify, such as an index book cover designatedgenerally at 15 (Fig. 3). As shown herein, the cover panel portions 1214are interconnected by rivets 16 or the like, and the outer edge of thepanel 12 is reverse-bent as indicated at 18 to provide a box-sectionedrim portion thereon.

In sectional view the holder 10 includes a generally box-sectionedintermediate or body portion 20 (Fig. 2.) extending from the skirtportion 11 and terminating in a downwardly directed front flange portion22 which terminates short of the skirt ii. The construction herebyprovides an open slot as indicated at 24 through which the bent shoulderportion 26 of the book panel 12 slide-fits when the holder is manuallysprung and elastically distorted to permit it to be forced onto the rim18 of the book cover into the operative position in Fig. 3. Thenceforththe skirt portion 11 and the body and flange portions 20-22 cooperate toelastically embrace the rim of the United States Patent 2,847,776Patented Aug. 19, 1958 book cover, thereby maintaining the holder in itsdesired position against accidental displacement.

Also as shown in Fig. 2, the body portion 20 is formed with an integralupstanding ridge 30, and the front flange 22 is provided with anintegral upwardly and then rear.- wardly inclined extension forming atop flange portion 32 which passes over the ridge 30 in slightly spacedrelation therefrom and terminates in a sectionally enlarged downwardlydirected head portion 34. Thus, the space under and adjacent the flangeportion 32 provides a flat chamber running lengthwise of the holder,adapted to accommodate a flat label or index strip as indicated at 35(Fig. 3). Preferably, a stock of labels will, be supplied in multiplestrip form intermediately perforated as indicated at 36. Thus, as shownin Fig. 3, a label, or index strip 35, subsequent to printing thereon ofthe desired indicia as by typewriter or the like, may be easily insertedin the holder while still attached to the label strip, by manuallydrawing the lowermost label edgewise longitudinally through the gapbetween the ridge 3% and the top flange 32 of the holder, until thelabel is properly positioned longitudinally and transversely under thetransparent flange 32. This brings the perforation line 36 intoalignment with the bead 34, whereupon the remainder of the label stripis easily severed from the label disposed within the holder by a simpleupward tearing motion along the perforation line 36.

The mounted label is thereby disposed in clear view through thetransparent panel portion 32; the ridge 30 pressing the label upwardlyagainst the bottom surface of the flange 32 and thereby elasticallybowing the label slightly. Thus, the label is maintained by reason ofthe elasticity characteristics of the material of the holder againstpossible unintended displacements of the label from the manuallyadjusted position thereof; yet when it is desired to remove and replacethe label this may be conveniently accomplished by simply pushing thelabel endwise while lifting slightly upwardly against the bead edge 34of the holder. This relaxes the spring grip of the holder upon the labeland permits it to be withdrawn or positionally adjusted in whateverdirection may be desired.

Although only one form of the invention has been illustrated anddescribed in detail hereinabove, it will be understood that variouschanges may be made therein without departing from the spirit of theinvention or the scope of the following claims.

I claim:

1. A label holder comprising an integral extrusion of transparentplastic having a sectional form including a flat skirt portion, abox-sectioned body portion including a front flange terminating short ofsaid skirt portion and defining therebetween a mounting gap, a ridgeextending upwardly from the rear side of said body portion, and a topflange extending generally parallel in spaced relation to said bodyportion and over said ridge whereby to define a label holding chamberbetween said body portion and said top flange into which a label may beinserted upon elastic deforation of said top flange relative to the bodyportion;

2. A label holder comprising an integral fabrication of transparentplastic material having in transverse sectional form a skirt portion, abox-sectioned intermediate portion extending from one side of said skirtportion including a first flange terminating short of said skirt portionand defining therewith a mounting gap therebetween, a ridge extendingfrom adjacent the side of said intermediate portion opposite said firstflange away from said skirt portion, and a second flange extending fromsaid first flange across said intermediate portion in spaced relationthereto over and beyond said ridge, said second flange being elasticallydeformable away from said intermediate portion and defining therewith alabel holding chamber.

3. A label holder comprising an integral extrusion of transparentplastic having a sectional form including a flat skirt portion, abox-sectioned body portion including a front flange terminating short ofsaid skirt portion and defining therebetween a mounting gap, a ridgeextending upwardly from the rear side of said body portion, and a topflange extending generally parallel in spaced relation to said bodyportion and over said ridge whereby to define a label holding chamberbetween said body portion and said top flange into which a label may beinserted upon elastic deformation of said top flange relative to form askirt portion, a box-sectioned intermediate por- 7 tion extending fromone side of said skirt portion including a first flange terminatingshort of said skirt portion and defining therewith a mounting gaptherebetween, a ridge extending from adjacent the side of saidintermediate portion opposite said first flange away from said skirtportion, and a second flange extending from said first flange acrosssaid intermediate portion is spaced relation thereto over and beyondsaid ridge, terminating in a bead portion extending toward saidintermediate portion and said second flange being elastically deformableaway from said intermediate portion and defining therewith a labelholding chamber.
